So, this may seem to be an odd question, and it probably is. In terms of standard fantasy RPGs like D&D, AD&D, Pathfinder, and OSR what really differentiates a zombie from a skeleton in terms of undeath? Is it just that it has skin where a skeleton does not. So if a zombie loses all of its skin does it then become a skeleton? A variant zombie?

Rawr is from a misfit line of minis called Arcane Legions. Rawr isn't his real name, but I can't be bothered to find out what it was. So now he's Rawr.
I picked up some Arcane Legions cheap, just to check them out. Almost all of them went straight into the Bucket of Shame. You can probably see why. The non-paint-job is pretty awful.
I wanted to practice slathering paint on something, so I dug into the Bucket of Shame to select a victim. Rawr kinda grabbed me. The scuplt is actually kinda neat. There's a lot of detail, at least. Not that this paint job would show any of it off.
So, after a good scrub, I slobbered (is this the correct, technical term, Buglips?) some 9236 Black Green / Green Shadow liner on him.
Then started blocking out blocks of color into their respective blocks.
Fur parts and club with 9268 Volcano Brown.
Leather parts, including club handle with 9250 Dusky Skin Shadow.
Clothes 9201 Orange Brown.
Skin 9220 Olive Shadow.
He looks like an escaped convict still wearing what's left of his prison jumper. Given Rawr's lack of impulse control, this is entirely plausible. At least his skin is all the same color now, and you can sort of tell where one element stops and another begins.
I'm still waiting for my KickStarter paints, so I don't have many colors to work with right now. Just stuff I've been picking up on sale. So I have 3 different purples, the olive skin triad, and some browns and greens. Yeah. So that's why he's wearing orange.
Lessons learned: Start inside and work out. Duh. I started with the fur and worked down, finishing with the skin. Probably better to go the other way with that.
Also, photos will show every flaw. He didn't look half bad in hand. The photos are rather unflattering. Oh well.
Next up will be to do some washes and see where things go from there.
